Sencha Cmd 5.0 issue - urgent, please help!

I have an issue and it is affecting my soon to be production deployment. Suddenly

$app_name.app.redirectTo stopped working

I upgraded to Sencha Cmd 5 and touch 2.3.1 now $app_name.app.app does not evaluate to anything after a production build. It works fine locally. It gives me

TypeError: 'undefined' is not an object (evaluating '$ap_name.app.redirectTo')

I changed all my redirectTo's to fireEvents in my controllers but it seems it is complaining about the touch code now. Do you have any idea where the app name gets set in the production build?
